Comparison Operators

edit

Elasticsearch SQL supports the following comparison operators:

  • Equality (=)
SELECT last_name l FROM "test_emp" WHERE emp_no = 10000 LIMIT 5;
  • Inequality (<> or != or <=>)
SELECT last_name l FROM "test_emp" WHERE emp_no <> 10000 ORDER BY emp_no LIMIT 5;
  • Comparison (<, <=, >, >=)
SELECT last_name l FROM "test_emp" WHERE emp_no < 10003 ORDER BY emp_no LIMIT 5;
  • BETWEEN
SELECT last_name l FROM "test_emp" WHERE emp_no BETWEEN 9990 AND 10003 ORDER BY emp_no;
  • IS NULL/IS NOT NULL
SELECT last_name l FROM "test_emp" WHERE emp_no IS NOT NULL AND gender IS NULL;
